Safe Operation Rules
Please take a few minutes to read our instructions before
you install and use your air conditioner. This will help you
obtain the full value from your air conditioner. It will also
help you avoid any needless service costs that result from
causes we cannot control and cannot cover in our
warranty.
Follow these rules and the instructions carefully. Failure to
do so could cause a malfunction of the air conditioner,
resulting in injury, death and/or property damage.
Check local codes and utility standards. The installation
must comply with their rules.
Always shut off electric power before making unit
connections or removing any panels.
During installation or servicing, be extremely careful to
avoid injury. Components may have sharp edges or
protrusions which can cut you. Tubing and compressor
contain high pressure refrigerant—they must not be
exposed to high temperature or be punctured.
